2013 MERCEDES-BENZ GL450

2013 Mercedes-Benz GL450; it started with the activation of the vehicle's check - engine light. The Mercedes-Benz service advisor diagnosed the issue as oil intrusion into the vehicle's engine wiring harness. The estimated cost to repair was quoted as $7,0000.00. This resulted in the replacement of the engine wiring harness, four (4) Lambda sensors, four (4) camshaft hall sensors and four (4) camshaft solenoids. This trouble could cause engine failure or misfire if not corrected. Driving the MB GL450 in this condition is a safety issues for anyone driving on the road. Researching on the internet about MB GL450/550 engine oil intrusion into the engine wiring harness is a common problem.

AS YOU STATED ABOVE THE AIR CONDITIONING IS NOT A REASON A DRIVER WOULD LOOSE CONTROL UNLESS YOU HAVE A MERCADES THAT IS LEAKING GAS AND MY KIDS AND PASSANGERS ARE SICK AND PASSING OUT AND SO AM I. THIS HAS BEEN GOING ON ALMOST 3 YEARS. GOES TO DEALERSHIP AND THEN SITS BECAUSE THEY NEVER FIX IT. FINALLY A LAW SUIT WITH PEOPLE HAVING SAME PROBLEM ENTERED THE CLASS ACTION SUIT NOTHING. TOOK THE CAR BACK AND THEY SAY NOW THE TOXIC GAS LEAKING OUT OF FAULTY A/C UNITS THAT MERCEDES WAS SUED AND CONSUMERS WON BUT NOW WON'T FIX THE PROBLEM. SO I NOW HAVE SEVERE ASTHMA MY KIDS NOW HAVE BREATHING ISSUES AND WON'T DRIVE A SICK CAR. A/C UNITS ARE TO BE CONTAINED AND HOLD ANTI-FREEZE THAT IF INHALED AS IT IS LEAKING OUT OF THE NON CONTAINED UNIT IS TOXIC, A CARCINOGEN, SAME TOXIN USED IN NERVE GAS AND IT IS DEADLY AND MERCEDES DOES NOT FIX IT OR CARE. THIS HAS GONE ON FOR YEARS AND IS A NIGHTMARE. THEY MADE A SETTLEMENT BUT THEN THEY DON'T DO WHAT THE JUDGE SET FORTH IN THE SETTLEMENT AGREEMENT AND I AM NOT THE ONLY ONE;

Driver's side tire continues to leak air - note low tire pressure even with new tire replacement. Airmatic Suspension failure. Rear airbag suspension airbag. Compression also failed. Several complaints to dealer advising the car was bouncing up and down while in drive. Took vehicle to the shop with suspension complaints at the end of April 2021. We were told they did not find an issue with suspension but saw an issue with the sway bar. This cost $549.00. The week we brought the car home it was still bouncing up and down and we contacted the dealer again and was advised they did not find anything wrong. Within 2 weeks of having the vehicle, I was driving and the vehicle was violently bouncing up and down even traveling at a low level. We took the vehicle back and have not been advised now that they see the malfunction light for the suspension on they realize that's the issue. The suggested cost to repair only the rear is $4k. If the front and rear need repairs it over $7k. The issue is it appears this is a known issue for the Airmatic system and with a vehicle in this price range and under 90k miles - appears to be a issue with manufacturing. I was also advised this repair is no longer covered on their extended warranty.

WHEN ACTIVATION OF THE SUSPENSION LIFT SYSTEM. COMPRESSOR IS COOLING THEN A MALFUNCTION MESSAGE APPEARS ON THE SCREEN. VEHICLE SHAKES VIOLENTLY IN THE REAR UP AND DOWN AT LOW AND HIGH SPEEDS AND OVER ANY SMALL BUMPS IN THE ROAD. THIS CONCERNS ME FOR THE SAFETY OF OTHER OWNERS WHOM MAY HAVE THE SAME PROBLEM. 2013 MERCEDES BENZ GL 450 IS THE MODEL I OWN CURRENTLY AND IVE BEEN HAVING THIS PROBLEM FOR THE PAST 3 MONTHS AND I'M ALMOST SCARED TO DRIVE IT FOR FEAR OF SOMETHING CATOSTROPHIC HAPPENING. PLEASE LOOK INTO THIS PROBLEM. EVEN WHEN PARK AND ACTIVATING THE SUSPENSION SYSTEM THE ERROR MESSAGE STILL APPEARS.. I HAD A INDEPENDANT MECHANIC SAY ITS THE REAR AIR BAGS AND THE COMPRESSOR THAT HAS TO BE REPLACED BECAUSE OF IT BEING A 4 MATIC MODEL THE AIR LINE FROM THE COMPRESSOR IS NOT SUPPLYING THE REAR SUSPENSION WITH ENOUGH AIR TO LIFT THE VEHICLE THUS CAUSING THE PROBLEM THAT WE HAVE.

THIS CAR HAS LOT OF ISSUES WITH WATER PUMP, RADIATOR LEAK, LOT OF ENGINE PROBLEMS. OIL LEAK IT'S GOT LESS THAN 100,000 MILES. RADIATOR HOSES LEAK. CAR STOPPED ON MASS PIKE GOING TO ALBANY, NY TOOK IT TO BENZ OF ALBANY THEY SAID ENGINE MISFIRES NEEDS ENGINE REPLACEMENT AND IT WOULD COST $47,000 TO REPLACE. VERY VERY BAD ENGINES. I LEFT A VOICEMAIL ON BENZ CUSTOMER SERVICE AND NO ONE CALLED BACK OR SEND ME ANY TYPE OF RECALLS. VERY BAD SERVICE.
